Watch the area in the upper left of the Sun’s corona—a laterally oriented structure appears to balance itself above the Sun’s surface for at least two days.
The structure seemed to fade about halfway through the video, but then reappeared even clearer than before. This solar activity was imaged in a wavelength of extreme ultraviolet light.
